4Application filed November 26, 1923. Serial No. 676,988.`

T0 all whom t may concern Be it 4known that VILLMM E. SMALL, citizen yof vthe United States, residing at Brooklyn, in the county of Kings and State of New York, has invented certain new and useful Improvements in Heel Lifts, of which the following is a specification.

My invention relates to an article of .manufacture, viz; lifts, for building heels for boots and shoes, the same to be used in a deviceespecially provided therefor, to which more especial reference is made to my application for patent for a method and apparatus for building heels, disclosed in said application filed February 1st, 1921, serially numbered 441,538,`and patented on March 25, 1924, #1,487,980, wherein layers of flat or ta.-

pered lifts of varying sizes are arranged in a series of successive layers, differing in diameter and thicknesses from each other for the particular purpose, each vand every lift being placed over, and is held secure to the others by suitable adhesive material, and the complete assembled heel removably held in e a heel lift made of a single piece of leather,

or made up of scrap pieces, with interlocking means for holding the pieces .together without other agencies, and provide the saine` with locking means therein or thereon, wherebythe workman Will not be hampered in assembling the various size lifts to build they desired heel. Mylo'ck formingthe interlocking means hold the several pieces together asv securely as if Athey were glued.

Again, by having my locking means secured to each and every lift, prevents the slipping and sliding of the same in any direction,

when assembled and ready for the first pressure to be applied, yet to have such assembled mass as readily removed from the de-l vice at theproper time.

My invention further consists in certain' novel details of construction and combination and arrai'igementsl as will be hereinafter described and pointed out particularly in the appended claims.

The invention as at present preferred will be more clearly understood by reference to the drawing which illustrates merely an example of means for putting my invention into practice, and wherein z-Fig. 1 is a view of a lift provided with a curved breast wherein is provided a suitably shaped lock for holding them together, rthe llift,

after being thus assembled, is readyto ybe cut by thedie as shown by dotted lines, illustrating another style of opening .adapted to receive a suitable key; Fig. 4 is .a like View showing a plurality 'of pieces secured together by modified forms of my locking means, the lift as it would appear when finished, is illustrated in dottedplines, showing ,the locking meansapplied to the 'breast of the lift, and Fig". 5 is a further niodiiica' tion showing rectangular"openings, within whichthe pointed key grips and holds `tight against ,the sidewalls of the openings.

Similar numerals of reference indicate like parts in the several `figures ofthe dra-W- ing.

The building of heels for various styles of slices, `having as many varieties of heels as `there are styles in shoes, becomes a serious question to the manufacturer, and in many cases'where it becomesimpracticable tobuild some styles of heels Iof layers, such "for instance as 'the French heel as was customary, yit having" been jfound cheaper and much Veasier to casty them of metal lor Vcut them from wood, thus avoiding Vthe loss of labor and material;y But in other styles of heels there is at present a great amount ofwastage yof both time .and labor, to say nothing of material, by reason ofthe systems now 'employed in manufacturing heels. To make a good perfect heel `without nails, and other sition, the whole mass after being assembled,

is then ready for the pressurev to be applied.

By providing the various lifts 6, be they the flat or the tapered or wedge variety, with a curvedbreast that fits a corresponding curve in the assembling device, (not shown) and providing the breast of the lift with a dove-tail slot 7, which is adapted to receive and house a suitable key to {it therein. It will be readily seen how each and every lift when placed one on top yof the# to the assembling'idevice, will prevent move-f ment'of any of the several layers, this notwithstanding that there may be one or more wedge shaped lifts therein.

Referring to Fig. 2, is shown a lift provided ywith Va flat face or breast 8 and havinga projecting part or key 9, that is adapted tol fit into a Corresponding opening in the breast plate (not shown) inthis modikey 9-holding the face of the lifts tightly against the breast plate, thus assisting materially in holding the lifts against movement.

Referring to Fig. 8 in which is shown the adaptability of my lock applied to hold to receive the projection, when the pieces are placed together they fit so perfectly thatl there is not the slightestdanger of their pull- Aing apart. Again in Fig.` l is shown the interlocking idea used when two or more pieces of scrap leather are used, the rvarious styles of locks 12, '13 and 14 shown, being yonly illustrative of the many different forms that may be employed for locking the various lifts to the breast plate, which plate lwouldbe provided with the necessary opening or key to form the other member of the lock that would hold the mass of layers together. As before noted, by using -my in terlocking means on scrap piecesof leather,

. it obviates the necessity of pasting, stapling or otherwise securing the. pieces together, and when once assembled together will remain in that position even when beingapplied to the mass of preceding lifts.

:Referringnow to Fig. 5 it will be seen that thelift is provided with two rectangular openings. 15 Which may be punched, stamped .or otherwise placed therein,.the keyithat is used inthis style of opening may be'of the T shaped variety, it* having beenfound in the actual working of lifts of this style, that the outer 4edges of the T shaped key beingy slightly sharpened, that thesame would embed themselves in the side walls of the cut- Vouts and hold the lifts secure to the breast Vmay assume, be it, as has been noted, foi ication, as in the other designs, the vari` ous lifts are securely held in position by the either securing separate pieces of leather together to form lifts, or for securing said lifts in assembled built up mass My cooperative lock insures the various styles of lifts being held permanently' in their position while pressure is applied,"and while those only that were thought the more important are illustrated, yet it is to be understood that 'various other forms of locks may be devised, but that all such other means are to come within the scope of the claims.

1. A heel lift provided with locking means adapted to engafre withxcooperative locking means associated with the heel assembling apparatus. n v

2. A heel lift provided with locking means on an edge 'thereof adapted to engage with cooperative means associated with the heel assembling apparatus whereby tol hold the lift against movement.

3. A heel lift provided with locking meansv on the breast thereof adapted to engage with coo erative4 locking `means on the heel assem ling apparatus whereby to hold the lift `against movement during the assembling operation. Y 4. A heel blank comprising a plurality `of superposed lifts each of which is provided with locking means which iengage with cooperative means associated lwith the assembling lapparatus during the produc-l tion of the blank, said locking means beingr subsequently removable during thel finishingstep.

5. A heel blank comprisinga plurality of superposed lifts each of which is pro# vided with locking means which engage with arcommon cooperative locking means associated with the assemblinoV apparatus during the productionof vthe blank.

In testimony whereof I ailix my si ature.' WILLIAM E. S Y L.
